Liver Cancer

Overview

Liver cancer, most commonly hepatocellular carcinoma (HCC), arises from liver cells and is one of the leading causes of cancer-related deaths worldwide. It is particularly common in Asia due to the high prevalence of chronic viral hepatitis.

Unlike many cancers, liver cancer often develops in an already diseased liver (cirrhosis), making early detection crucial because treatment options and cure rates depend heavily on stage at diagnosis.

Causes and Risk Factors

Most liver cancers occur due to long-standing liver damage and regeneration cycles. Major causes include:

  • Chronic Hepatitis B infection

  • Chronic Hepatitis C infection

  • Liver cirrhosis (from any cause)

  • Alcohol-related liver disease

  • Non-alcoholic fatty liver disease (NAFLD / NASH) linked to diabetes and obesity

  • Aflatoxin exposure (contaminated stored grains)

  • Metabolic disorders (hemochromatosis, Wilson’s disease)

Among these, chronic viral hepatitis remains the most important risk factor in India.

Common Symptoms

Early liver cancer may not produce symptoms and is often detected during surveillance scans. When symptoms appear, they may include:

  • Unexplained weight loss

  • Loss of appetite

  • Persistent upper abdominal pain (right side)

  • Abdominal swelling (ascites)

  • Yellowing of eyes and skin (jaundice)

  • Fatigue and weakness

  • Sudden worsening of previously stable liver disease

Because symptoms appear late, screening in high-risk patients is essential.

Screening and Prevention

Liver cancer is one of the few cancers where regular surveillance significantly improves survival.

Who should undergo screening:

  • Patients with cirrhosis

  • Chronic Hepatitis B carriers

  • Chronic Hepatitis C patients

  • Long-standing fatty liver disease with fibrosis

Recommended screening:

  • Ultrasound abdomen every 6 months

  • Serum AFP (alpha-fetoprotein) blood test

Prevention strategies:

  • Hepatitis B vaccination

  • Early treatment of Hepatitis B and C

  • Avoid alcohol abuse

  • Maintain healthy weight and control diabetes

  • Safe food storage to prevent aflatoxin exposure

Early detection allows curative treatment in many patients.

Treatment Approaches

Treatment depends on tumor size, number, liver function, and overall health.

Curative options:

  • Surgical resection (tumor removal)

  • Liver transplantation

  • Ablation (RFA / Microwave ablation) for small tumors

Locoregional therapies:

  • TACE (Transarterial chemoembolization)

  • TARE / Y-90 radioembolization

Radiation Therapy:
Modern high-precision radiotherapy such as SBRT is increasingly used for inoperable tumors.

Systemic therapy:

  • Targeted therapy (sorafenib, lenvatinib)

  • Immunotherapy combinations for advanced disease

Cutting-Edge Cancer Care by Dr. Rajesh Natte

Dr. Rajesh Natte, an experienced radiation oncologist, treats gastrointestinal malignancies including colorectal and liver cancers using advanced precision radiotherapy.

Using Image-Guided Radiotherapy (IGRT), Intensity-Modulated Radiotherapy (IMRT), and Stereotactic Body Radiotherapy (SBRT), he delivers ablative radiation doses directly to liver tumors while preserving normal liver tissue — critical in cirrhotic patients.

With 4D respiratory motion management, adaptive planning, and AI-assisted contouring, moving liver tumors can be targeted accurately despite breathing motion. This enables:

  • Non-invasive tumor ablation

  • Preservation of liver function

  • Reduced complications

  • Short treatment duration (few sessions)

Patients unsuitable for surgery can achieve excellent local control with this modern approach.

Conclusion

Liver cancer is serious but often preventable and treatable when detected early. Vaccination, regular surveillance in high-risk individuals, and timely intervention are key to improving survival.

With advanced radiotherapy technology and individualized treatment planning, Dr. Rajesh Natte provides world-class precision cancer care — helping patients fight liver and colorectal cancers safely and effectively.
